This question has probably been asked before but its a good question and I'd like a shot at dealing with it. Let's get down to basics. Never mind the Bible at this stage. I would like all those atheists or agnostics out there to state precisely what they would regard as satisfactory proof to them that God exists. If you believe that there is no such thing as God what would it take to change your mind, (assuming it is open to be changed of course)?
